BUILDING CONSTRUCTION.

Specification of Letters-Patent.

Patented Feb. 3, 1920.

Application filed August 6, 1919. Serial No. 315,577.

To all whom it may concern:

Be it known that I, JOHN LALLY, a citizen of the United States, residingat Boston, Suffolk county, Massachusetts, have invented new and usefulImprovements in Building Constructions, of which the following is aspecification.

My invention relates to improvements in building'construction of thereinforced concrete type and constitutes an improvement on the structureof my Letters Patent No. 1,258,917, dated March 12, 1918, and it is myobject to cheapen, lighten, simplify and strengthen the structure showntherein and to make additional provision for reinforcing the flooradjacent the column and provide means for holding the reinforcing barstaut and tie the columns together into a rigid,

' braced structure.

- of slots 2 inside of the column above the slot.

that the crown is In the drawing Figure 1 is a side view of my improvedconstruction provided with a circular crown, partly in section; Fig. 2 atop view of the structure of Fig. 1-; Fig. 3 a section on the line 3-3of Fig. 1; Fig. 4 a plan view of one form of floor reinforcing; Fig. 5 atop view of my construction with a square crown, showing the reinforcingbars and adjusting means therefor; Fig. 6 a sectional view of thestructure of Flg. 5; and Fi 7 a detail View of the reinforcing bar adusting means.

I employ a column 1 as the foundation of my structure and provide itwith a plurality near the top. A bracket late 3 is inserted in each ofthese slots an has an upwardly extending lug 4 engaging tn; crown 5,circular as shown in Figs. 1, 2 and 3 and square in Figs. 5, 6 and 7, isconnected to the brackets by struts 6 extending from the crown to thebrackets. This leaves the crown open and, as the slots 2 are so locatedflush with the top of the column, I am enabled to superimpose the upperstory column 7 on the lower column with its base flush with the upperfloor.

In practice the column 1 is filled with plastic material like concrete,thereby binding the brackets 3 in position and strengthening thestructure.

In a building the column and crown are set up and wire reinforcingfabric 8 is laid in position to form the floor reinforcement.

Reinforcing rods of any desired shape 9 are arranged radially over thecrown and extend under the wire fabric to better disthe outside diametertribute the loads and strengthen the structure where the floor joins thecolumn.

The wire fabric, reinforcing rods, crown and outside of the column arethen embedded in the plastic material, generally concrete, and theresultant structure is a reinforced but light,

monolith which is not only strong,

only by and the floor space is diminished of the column.

In the modification shown in Figs. 5, 6 and 7 a square crown 5' isemployed and is provided with a tension plate 10 on the upper .face ofthe crown and preferably wider than the top face. This tension plate hasa plurality of slots 11 along its length at right angles to its longside and is secured to the crown by means of bolts 12.

The reinforcing bars 9 have hooks'13 on their ends and these hooks assover the inner edge of the tension p ates and engage it.

After the columns have been set up the hooks 13v are placed over thetension plates of'adjacent columns and anchored thereto so that onpulling up on the tension plates and bolting them in place thereinforcing bars 9 are held tautly in place and unite the columns into aself supporting, metallic structure around which the concrete may bepoured.

I claim:

1. Building hollow column slotted below the top, a bracket with anupwardly extending lug in each slot, a crown approximately flush withthe top of the column, struts connecting the crown and brackets and aplastic filling within the column engaging the brackets. I

2. Building construction composed of a hollow column slotted below thetop, a bracket with an upwardly extending lug in each slot, a crownapproximately flush with the top of the column, crown and brackets, aplastic filling within the column engaging the brackets and plasticmaterial covering and embedding said structure. a

3. Building construction composed of a hollow column slotted below thetop, a bracket with an upwardly extending lug in each slot, a crownapproximately flush with the top of the column, struts connecting thecrown and brackets, means on the top of the column for engaging asuperimposed column and plastic material within said column engaging thebrackets.

solid struts connecting the ioo 4. Building construction composed of ahollow column slotted below the top, a

bracket with an upwardly extending lug in each slot, a crownapproximately flush with the top of the column, struts connecting thereinforcing barsbracket with an upwardly extending lug in each slot, acrown approximately flush with the top of the column, struts connectinthe crownand brackets, a plastic filling within the column engaging thebrackets, a tension plate adjustably secured to the crown andreinforcing bars anchored to said plate.

7. A plurality of adjacent columns each having an open top crownthereon, tension plates adjustably secured to the crowns, andreinforcing bars anchored to said tension plates and extending fromcrown to crown whereby the columns are united into an integralstructure.

In testimony whereof, I have signed my name to this specification.

JOHN LALLY.
